STENCIL PLATE.

SAMUEL C. SUMNER, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN STENCIL-PLATES a section on the line or w of Fig. 1.

Stencil-plates have been made by cutting the letters upon separate plates and arrangin g them in succession in the order-required the one next to the other. This was objectionable, as the paint, or whatever coloringfluid was used, went through the joints or cracks between the separate letters and disfigured the object being marked.

To remedy this is the object of my invention, which consists in the employment of a foundation plate or holder of peculiar construction, into which the plates having the. letters are slid, as will now be more fully described.

In the accompanying drawings, A is the foundation plate or holder, which is secured to a strip of wood, B, which answers the double purpose of handle and stiffener of the plate. Holes 0 are then cut through the plate, leaving the bars or narrow divisionplates e between them. Slits d are then cut through the plate opposite to the holes C, so that the plates 9, Fig. 2, when inserted shall abut against each other beneath the bars e, or shall overlap each other, and thus prevent the marking-fluid from penetrating between the plates g and disfiguring the article being marked.

The plate A is turned up on the strip B, Fig. 3, which thus forms a stop, against which .the plates 9 rest, thus keeping them in line.

At the left hand of Fig. 1 the letter-plates g are withdrawn from the holder. At the right hand of the same figure they are in place.

What I claim as my invention, and desire to secure by Letters Patent, is

The holder A, with its holes 0, slits d, and bars 0, in combination with the letter-plates g, for the purpose described.
